MONKEY-WRENCH.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed January 15,1907. Serial No. 852,383.

To all whom, it may concern.-

Be it known that I, DAVID GOBEL, a citizen of the United States, residing at Zanesville, in the countyj of Muskingum and State of Ohio, have invented a new and useful MonkeyJVrench, of which the following is a specification. I

My invention relates to improvements in monkey-wrenches; and the object of my invention is to provide a ratchet-and-pawl mechanism for rotating the jaws. I attain this object by the mechanism illustrated in the accompanying drawings, in whicl1- Figure 1 is a front view of my invention; Fig. 2, a back view with parts broken away; Fig. 3, a sectional view; Fig. 4, a view in detail of the ratchet-wheel, &c.; Fig. 5, a back view of a jaw and pawl, and Fig. 6 a side view of a jaw and pawl.

Similar numerals refer to similar parts throughout the several views.

1 is the handle and body, provided with socket 2, which holds socket-bolt 3, which is provided with socket 4, which is adapted to receive the bolt carrying the nut to be turned. Socket-bolt 3 is fixedly and concentrically attached to ratchet-wheel 5, which is fixedly and concentrically attached to rotating disk 6, which is provided with double beveled groove 7, adapted to receive and retain jaws 8 8, carrying stationary pawls 9 9, provided with spiral springs 10 10, which secure the engagement of the teeth 11 11 of pawls 9 9 with the ratchet-tracks 12 12, which are formed in the bottom of double beveled groove 7. The body 1 is also provided with sockets 18 18, which hold reciprocating pawls 14 14, which are provided with actuating-springs 15 15, which are adapted to adjust pawls 14 14 when locking-pins 16 16 are thrown off from shoulders 17 17 into slots 13 13.

The operation of my invention is as follows: With the thumb and finger adjust jaws 8 8 to the nut, compressing spiral springs 10 10 when necessary to move the jaws from the center of the disk, and if the handle of the wrench is to be moved toward the right in turning the nut throw lockingpin 16 of reciprocating pawl 14 onto shoulder 17. Then move the body of the wrench to the right, and reciprocating pawl 14 will engage ratchet-Wheel 5 and turn the nut,

when as often as desired the hand can be returned to its first position and the operation of turning the nut can be repeated without disengaging the jaws from or again engaging them with the nut.

I claim 1. In a monkey-wrench,the combination with the body carrying reciprocating pawls, of a circular disk provided with a ratchetwheel and with a double, undercut groove having in the bottom thereof ratchet-tracks, and with sliding jaws having double, beveled shanks, and having stationary pawls adapted to engage said ratchet-tracks; said reciprocating pawls being adapted to engage said ratchet-wheel, substantially as described.

2. In a monkey-wrench, the combination with the body carrying reciprocating pawls, of a circular disk provided with a ratchetwheel and with a double, undercut groove having in the bottom thereof ratchet-tracks, and with sliding jaws having double, beveled shanks, and having stationary springpawls adapted to engage said ratchetrtracks; said reciprocating pawls being adapted to engage said ratchet-wheel, substantially as described.

3. In a monkey-wrench, the combination with the body carrying reciprocating pawls, of a socket-bolt and of a circular disk provided with a ratchet-wheel and with a double, undercut groove having in the bottom thereof ratchet-tracks, and with sliding jaws having double, beveled shanks, and having stationarypawls adapted to engage said ratchettracks; said reciprocating pawls being adapted to engage said ratchet-wheel, substantially as described.

4. In a monkey-wrench, the combination with the body carrying reciprocating pawls and provided with pawl-locking shoulders, of a circular disk provided with a ratchet-wheel and with a double, undercut groove having in the bottom thereof ratchet-tracks, and with sliding jaws having double, beveled shanks, and having stationary pawls adapted to engage said ratchet-tracks; said reciprocating pawls being adapted to engage said ratchet-wheel and said pawl-locking shoulders, substantially as described.

DAVID GOBEL.
